[ Detailed description ] of the invention

The detailed description and technical content of the present invention are described below with reference to the drawings, which are, however, provided for reference and illustration only and are not intended to limit the present invention.

As shown in fig. 1 to 2 and fig. 7 to 8, the present invention provides a mobile electronic device, comprising: a main frame 1, a back cover 3, a door cover 5, a functional module 6, and a stopper 7, and more specifically, a touch panel 2. The door cover 5, the functional module 6 and the stop member 7 are used to be combined together into an expansion assembly S, through which various required functions can be selectively expanded, for example: bar code reader, fingerprint identifier, photographic lens and infrared communicator.

The main frame 1 has two opposite frame surfaces 11, 12 and a plurality of side edges 13 connected between the two frame surfaces 11, 12, and a motherboard, not shown, is disposed in the main frame 1. Although the touch panel 2 is stacked and fixed on one of the frame surfaces 11, in other embodiments not shown in the drawings, a display screen or other electronic products may be fixed on the frame surface 11, which is not limited by the present invention.

The back cover 3 is stacked and fixed on the other frame surface 12, so that the back cover 3 covers the main frame 1. The back cover 3 is provided with an expansion window 33 and has an outer cover surface 32 exposed outwards. The expansion window 33 communicates with the main frame 1, specifically, the motherboard. The expansion window 33 can be disposed at any position of the back cover 3, and preferably, the disposed position corresponds to the frame surface 12 of the main frame 1 and one side 13 of the plurality of sides 13 (see fig. 1 and 7) as shown, so that the expansion assembly S of the present invention can utilize the space in the frame surface 12 and the space in one side 13 at the same time, thereby achieving the effect of fully utilizing the space.

The door cover 5 is arranged corresponding to the expansion window 33 and is fixed on the outer cover surface 32 of the back cover 3, so that the door cover 5 covers and closes the expansion window 33. The door 5 has an inner side and an outer side opposite to each other and neither of which is denoted by a reference numeral.

The functional module 6 is disposed inside the door 5, and the functional module 6 can be electrically connected to the motherboard through the expansion window 33, for example, but not limited to, by using a plurality of flexible printed circuit boards (FPCs, flexible Printed Circuit) or a plurality of flexible flat cables (FFCs, flat Flexible Cable) not shown in the figure. As shown in fig. 6, an outward facing side of the functional module 6 has an operation interface 61, and the operation interface 61 is correspondingly located on the outer side of the door 5 (as shown in fig. 6, actually is correspondingly located on the outer side 522 of the side plate).

It should be noted that, after the door 5 is fixed to the back cover 3, the outer side of the door 5 is directly exposed outside the entire mobile electronic device, so that the functional module 6 is easily forced to retract and move toward the inner direction of the mobile electronic device due to an external force (such as an impact force generated by the crash or fall of the entire mobile electronic device).

The stopper 7 is provided on the inner side of the door cover 5 for this purpose, and the stopper 7 is abutted against an inner side (opposite to the outer side) of the functional module 6 to stop the external force. Wherein, the door cover 5, the functional module 6 and the stop member 7 are combined together to form the expansion assembly S.

Thus, as shown in fig. 4, even if the expansion module S encounters an external force, since the existing stopper 7 stops the functional module 6 in the opposite direction of the external force, it can be ensured that the functional module 6 is never moved inward relative to the door cover 5 by the influence of the external force, and thus it can be ensured that the functional module 6 is not disabled or damaged by the inward movement.

The present invention is not limited to the structure of the door 5, but in the present embodiment, the structure shown in fig. 3 to 6 will be described as an example. The door 5 mainly comprises a back plate 51 and preferably comprises a side plate 52 bent and connected to the back plate 51, so that the shape of the door 5 can correspond to the shape of the frame surface 12 and one of the side edges 13 (see fig. 1,2 and 7). The inner side of the door 5 includes a back plate inner side 511 and a side plate inner side 521 respectively belonging to the back plate 51 and the side plate 52, and the outer side of the door 5 includes a back plate outer side 512 respectively belonging to the back plate 51 and a side plate outer side 522 respectively belonging to the side plate 52.

In order to further enhance the anti-collision or anti-drop capability of the expansion module S (particularly, the functional module 6), as shown in fig. 7 to 8, a plurality of protrusions 14 may be protruded around the frame surface 12 of the main frame 1, for example, a protrusion 14 is protruded at four corners of the frame surface 12, and the protrusion height of each protrusion 14 is higher than the back plate outer side 512, so that even if the external force is directed to the back plate outer side 512, only each protrusion 14 will strike the back plate outer side 512, and thus the anti-collision or anti-drop capability of the back plate outer side 512 is enhanced. Of course, the protrusions 14 may be disposed on the outer side 32 of the back cover 3 (not shown), which is not limited by the present invention.

As shown in fig. 1 to 2 and fig. 7 to 8, at least one protrusion 131 may be protruded on one side 13 of the main frame 1, and the protrusion 131 may protrude higher than the outer side 522 of the side plate, so that even if the external force is directed to the outer side 522 of the side plate, the external force only hits the protrusion 131 and does not hit the outer side 522 of the side plate, thereby improving the anti-collision capability or the anti-falling capability of the outer side 522 of the side plate. Of course, as shown in fig. 1, the protruding portion 411 may be disposed on one side 41 of a clip 4, so as to enhance the anti-collision or anti-falling ability; specifically, each side 13 of the main frame 1, the touch panel 2 and the back cover 3, which are overlapped with each other, is respectively clamped with a clamping piece 4, and the side 41 of one clamping piece 4 is convexly provided with the convex part 411; the two modes described in this paragraph can be implemented separately, and in this embodiment, the two modes are implemented together: the clamping member 4 provided with the convex part 411 is correspondingly sleeved on one side 13 provided with the convex part 131.

In order to further improve the blocking strength and the blocking stability of the blocking member 7, as shown in fig. 3 to 6, a blocking body 5311 may be further added on the inner side of the door cover 5, and two opposite ends of the blocking member 7 respectively abut against the blocking body 5311 and the inner side of the functional module 6, so as to improve the blocking strength and the blocking stability.

In the above description, the structure of the blocking body 5311 is not limited to the above description, but in this embodiment, a concave groove 53 is concavely formed on the inner side of the door 5, so that a surrounding groove peripheral wall 531 can be formed around the concave groove 53 on the inner side of the door 5, and one portion (the portion facing the inner side) of the groove peripheral wall 531 is the blocking body 5311, so that the blocking body has the best blocking strength and blocking stability.

Next, in order to enable the stopper 7 to perform a stop in the recess 53, the structure of the stopper 7 may include a first abutting portion 71, a second abutting portion 72, and a connecting portion 73 connected between the first abutting portion 71 and the second abutting portion 72. The first abutting portion 71 and the second abutting portion 72 are respectively bent relative to two opposite ends of the connecting portion 73, wherein the shape of the first abutting portion 71 and the bending angle are corresponding to the inward direction and are beneficial to being attached to the inward direction, the shape of the second abutting portion 72 and the bending angle are corresponding to the blocking body 5311 and are beneficial to being attached to the blocking body 5311, and one surface of the connecting portion 73 is directly or indirectly attached to the bottom 532 of the concave groove 53 so as to generate better supporting force.

It should be noted that the recess 53 is formed on the inner side 511 and the inner side 521 of the back plate, and the outer side 512 and the outer side 522 of the side plate are relatively convex, so that the recess 53 is utilized to provide additional space for the functional module 6 and the stop member 7, thereby further solving the problem of limited usage space of the mobile electronic device.

In addition, as shown in fig. 4 to 9, in order to prevent water from penetrating into the functional module 6, a waterproof structure (not shown) must be added between the door cover 5 and the back cover 3. The waterproof structure comprises: the inner side of the door 5 may have a rib 54, and an outer surface 341 of the back cover 3 may have an elastic portion 35, where the elastic portion 35 may be directly formed on the outer surface 341, and an additional elastic pad or a waterproof foam may be added as shown in the figure, but not limited thereto. The external connection surface 341 surrounds the expansion window 33, and the elastic portion 35 covers the expansion window 33 through the door cover 5, so that the elastic portion 35 is pressed by the ribs 54 to the corresponding elastic recess, thereby having better water tightness and further achieving the waterproof effect.

The position of the waterproof structure is not limited in the present invention, and in this embodiment, the waterproof structure is as follows: the convex rib 54 is projected on the inner side 511 of the backboard and the inner side 521 of the side board together, and the convex rib 54 is surrounded by the corresponding concave groove 53; and a frame surrounding part 34 (see fig. 1) corresponding to the convex rib 54 and surrounding the corresponding expansion window 33 is arranged on the back cover 3, and the external connection surface 341 is formed on the outer side (on the exposed side) of the frame surrounding part 34. Wherein the frame surrounding portion 34 is bent with respect to the frame surface 12 and one of the side edges 13, so that the shape of the frame surrounding portion 34 can also correspond to the shape of the frame surface 12 and one of the side edges 13 (see fig. 1,2 and 7).

Therefore, as long as the door cover 5 is arranged corresponding to the expansion window 33 and fixed on the back cover 3, the external surface 341 of the frame surrounding part 34 is adjacent to the inner side (including 511 and 521) of the door cover 5, the elastic part 35 can be extruded by the convex rib 54 to be correspondingly elastically recessed, so that the waterproof effect is better, and the waterproof effect is further achieved.

In other embodiments not shown in the drawings, the ribs 54 and the elastic portion 35 may be provided in reverse: the same waterproof effect can be achieved by providing the ribs 54 on the external surface 341 and forming the elastic portion 35 on the door 5.

The foregoing description is only illustrative of the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, as all changes which come within the meaning and range of equivalency of the description and drawings are intended to be embraced therein.
